If a² + b² = c², then the triangle is right.

So we have (8)² + (11)² ? (13)²

(8)² is 64, (11)² is 121, and (13)² is 169.

So we have 64 + 121 ? 169

64 + 121 is 185 and we can see that 185 > 169.

This triangle would not be a right triangle.

In fact, it would be an acute triangle.

So no, it's not a right triangle.

Vikki [24]

First, let x be the number of hours it will take for Hector to finish the same job alone. This means that every hour, Hector can do 1/x of the job. The amount of work done by Shawn and Hector in 6 hours should be equal to 1 complete work. This can be expressed as,
(1/9 + 1/x)(6) = 1
The value of x is 18. Thus, Hector can to 1/18 of the job in one hour.

A hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. They sell 11 boxes that have 6 paintbrushes

grin007 [14]

Answer:

Step-by-step explanation:

The hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. This means that the total number of paintbrushes that was ordered is

12 × 9 = 108

Therefore, the total number of paintbrushes that the store has would be

200 + 108 = 308

They sell 11 boxes that have 6 paintbrushes each. This means that the total number of paintbrushes that they sold is

11 × 6 = 66

Therefore, the number of paintbrushes left would be

308 - 66 = 242

The manager's estimate is reasonable. They ordered about 120 paintbrushes and sold about 60 of them so they should have about 60 more paintbrushes than they started with.
